The last half has been on 15/47 gearing with a Kientech rear guide. The wear on the chain guide is less but it is still visible in the picture below. I think I was running with too much chain slack for a long time, too. I just recently removed the top roller but it had very little wear on it. The lower roller still spins freely so I do not think it is contributing much to this.




I did not realize my guide was taking such a beating until looking at that picture.
Yep , like the man said "Don't worry" mines been the same on the last 3 chains , then again i do a lot of dirty riding

She said the bike was checked by a mechanic and there is just normal wear and tear on the bike. I asked her if the bike produces any smoke --
she said that all dual sports produce exhaust/smoke.
That's funny. Have you ever watched a woman try to work a screwdriver, pliers or Cresent wrench? With the exception of my Sister, Greer, and two or three others on the site, ladies don't understand anything made out of metal, except expensive jewelery. White smoke is condensation burning off like any vehicle when cold. Smoke with a bluish tint is burning oil; not necessarily bad if it quits shortly after starting. Anything showing black is rich; you're seeing wasted fuel. It may be hard to start and won't idle without the choke; it's five years old and is probably full of stale gas. Open the gas cap and take a sniff, it should be obvious.

......what do you guys think of the price? I would think 768 miles on a 2007 DR650 is literally nothing for this type of bike..

Thanks again for the help..
Pics are good if you have them, here's how:

Being that new and low mileage, chances are very good it's in great condition. DRs are catching on and becoming hard to get at bottom dollar. If it's clean, someone will snatch it up if you hesitate. It doesn't matter what you pay for it, it wil make you smile for many thousands of miles: see my sig.

Anybody else have this kind of wear?

Should I stop worrying?
Yes stop worrying. That's normal chain wear. Somewhere back in this thread there were several photos from different imates showing that wear on different bikes. Some worse, some less. And too loose is always better than too tight. (get yer mind outta the gutter )

Past my bedtime.

Yeah, it's just the dirt wearing the links down.

Wet clay isn't so bad, some greases are actually clay based. High silica areas seem to knock them around more.

The dryer the chain, the more you'll see it.

My wife and I went by and saw their impressive facility and lots of tricked out bikes. A few days later I got a call from Gary Christopher at Ohlins - I had won the shock! That also created a problem because Ohlins does lot list a shock for the DR650. After a little research, Gary came up with a plan: they would try to adapt the Ohlins DRZ400 shock to my 650. The pictures below show the results. I've gone from a spring and a prayer to a very controlled rear suspension. Gary told me that the new shock is a very tight fit!





After about 2 rides it was clear that the new shock was a vast improvement and that I needed to upgrade my front forks. Rick Tannenbaum at Cogent Dynamics was extremely helpful and did the emulators / springs upgrade. Now the bike is much more balanced.

I just did about 50 miles of Forest Service roads today and I'm really impressed with the bike and the suspension. I had not planned to work on the forks or shock this year but I'm glad that I got lucky and that there are such great resources nearby. I've got nothing but great things to say about Gary at Ohlins and Rick at Cogent Dynamics.
Why don't you have a chat with him and see if he would be interested in doing a few more!! I for one would have one in a heart beat.

Yes, they are the best....and I must have them.
Those top clamps are great for off road. They tie the 2 handlebar clamps together and prevent them from twisting independently when the bar comes in contact with the ground.

Thanks for that. I guess I'm not the only one with this kind of chain wear. When I looked at my guide there was very little evidence of contact but with the stock rear sprocket it would not come as close as yours does with an oversize sprocket.

Thanks for the reply. I looked at the Megacycle web site and there is no listing for the DR, is yours a sportbike muffler adapted to fit?

Broke down in MO, need service manual help

My bike has decided it doesn't want to start after being parked a few days. It was running fine when I parked it last Thursday and has been running fine over 5K miles in the past month (see my ride report in my sig line). Luckily it decided to quit at our friend's house, so we're not stranded exactly, but I don't have a service manual with me.

Bike is a '96 with 24,xxx miles. I suspect the pickup coil has failed, it matches the symptoms of others with that problem, but I don't know how to check it without the manual. Can someone help me out with this? I have a meter, just need to know what, where, and how to check and what the readings should be.

It is getting fuel, spark, and air....so what next? Safety switches have all been bypassed long ago, it isn't the kill switch. I pulled the carb (twice) and cleaned it, it has fresh fuel and is flowing fuel just fine. Air filter is clean.

Any help would be greatly appreciated!

Does the engine turn over when hitting the start button? Seems to me that the PU coil failure results in no spark? I'll try to find that info.

I found this in Krusty's DR650 Index.

It turns over and cranks fine. It gets spark, but I don't know how strong the spark is or the timing of the spark. It is getting fuel, the plugs are wet when I pull them.

Seems simple...air, fuel, and spark...makes it hard to troubleshoot when I have all three!

Exactly.

......air, fuel, and spark.......

At the top right of this page, click 'search this thread', type "pick-up coil". You have to use the hyphen, the site drops any three letter search terms. There are a lot of trouble shooting ideas there.

edit: A healthy spark is a bright bluish white, a weak spark is yellow/orange.

If it has a spark then it's very unlikely that the pickup coil has gone bad.

I went and tested the spark again, it is very intermittent and when it does spark, it is very weak yellow, not the normal bright blue. I would say it is only sparking about every 8-10 revolutions, sometimes it will go twice as long.

I ordered a new pick-up with next day delivery, guess I'll just enjoy the A/C for another day and hang out with our friends. At least it broke here. The next day delivery was more than the pick-up, but still way cheaper than a tow or hotel room!
